To all whom it mag concern:

Be it known that I, ADOLPH WAHLE, a citizen of the United States, and airesident of Davenport, in the county of Scott and State of Iowa, have invented certain new and-useful Improvements in Casings for Mechanical Movements, of which the'followingis a full, clear, and exact description.

Heretofore the mechanical movements for washing-machines, churns, and similar machines, and particularly mechanism employed for converting the continuous rotary movement of a suitable-fly-wheel turned by the operator into a rotary reciprocal movement of the vertical stirrer-shaft, have been exposed and frequently children meddling with the same have been injured and clothing and articles of the wash accidentally caught thereby and chewed and torn.

The object of my invention is to house such mechanism in a cheap and economical manner without much addition to the supporting-frame said mechanism would have to employ in any event and so as to prevent rust and avoid the possibility of the above-indicated as well as other accidents. This I ac; complish by the means hereinafter fully described, and claims.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 is a plan view of the Fig. 3 is a vertical longitudinal central section. Fig. 4 is a section taken on line 4: 4, Fig. 3, looking in the direction of the arrows. Fig. 5 is a detail view of the lower section.

In the drawings, A represents a longitudinal trough-shaped frame the outer end of which is supported by spreading legs a a. and

terminates im-bearing b. Theopposite or inner end of this frame A terminates in a semispherical cup-shaped lower section B of the case in Whichit is designed to house mechanism for converting the continuous rotary motion of a shaft 0,-journaled in bearing 19 r and bearings, located near the opposite end of frame 'A, into a rotary reciprocal motion 1 of the perpendicular shaft D, journaled in bearing d in the center of the bottom of section B, and in bearing 6, diametrically opposite thereto in'the top of the upper section E of said case.

particularly pointed out. in the- The bottom section B is provided with a concentric boss f, down through the center of which the bearings of shaftD extend, and this boss extends downward a suitable distance below its plane of rest, so as to anchor and prevent its displacement in a horizontal position in any direction. On each side of this boss there extends downward from the sides of section B a short tubular column g 9, down through which a suitable screw is inserted and screwed into the material of its support. If desired, the upper ends of the bores of these columns may be countersunk to accommodate the heads of the screws.

The upper semispherical section E of the case corresponds in dimensions to the lower section B, and the annular edges of these sections B and E are brought together to form a butt-joint and are secured in this position by means of suitable boltst', extending through radial lugsj and is, projecting from the edges of said sections, respectively. At the point where the shaft 0 enters the case the upper section is provided with an inverted semicircular stub F, projecting therefrom parallel and concentric to shaft 0. The projection of this stub is such that it overlaps the adjacent end of bearing cof frame A and its parallel edges rest upon the side edges of the channel or gutter of said frame, which between bearing 0 and sectionB is slightly wider. V

At a point preferably between the bearings e of the vertical shaft D and bearings c of shaft 0, I provide the upper section with a grated opening G, the spaces between the bars of which are large enough to insert the nozzle of an oil-can and easily oil the mechanism housed within the case, and in the bottom of section B an opening his provided for draining off the superfluous oil. In order, however, to prevent the oil from getting into the bearing d of said lower section,l have provided the interior surface of ,said section with a suitable circular or other endless shaped bead H, which is eccentric to bearingsd and is so located as to cause the oil dripping from the actuating mechanism falling outside of.

it to drain into and out of opening it.

While I have illustrated and described the upper and lower sections of the case as semispherical, it is obvious they can be made other shapes to accommodate the peculiarities in the shape and disposition of the actuating mechanism, for while I have illustrated actuating mechanism which is described and claimed in Letters Patent of theUnited States granted to me July 22, 1902, I do not wish to be understood as limiting myself to an inclosing case or frame only for such mechanism.

What I claim as new, and desire to secure by Letters Patent, is-

1. Acasingformeohanicalmovementscomprising a supporting-frame having bearings therein for the drive-shaft, a lower hollow section at one end of said supporting-frame having bearings in its bottom arranged at right angles to the hearings in said supporting-frame, and an upper inverted hollow section, secured to said lower section.
